Vacuum evaporation: The principle is to heat the film material with an evaporator under vacuum conditions to vaporize or sublime it, and then the evaporated particle flow is directly shot toward the substrate, where it is deposited to form a solid film. Evaporation is also divided into electron beam evaporation, resistance evaporation, induction evaporation, etc.
Ion Plating: Ion plating generally refers to a coating method that generates a large number of ions during the coating process. During the film formation process, the substrate is constantly bombarded with high-energy particles, resulting in a very strong film layer with excellent strength and adhesion. When ion plating is used to create high-precision films, large ion particles can be filtered out, resulting in a highly structured and dense film.
The most common vacuum coating equipment coating technologies in daily life are these three. The specific one to choose depends on what film layer to be coated and what workpiece to be coated.
